In order to increase the output current level, we have fabricated a parallelized pump with two gate-tunable quantum-dot pumps based on GaAs/AlGaAs heterostructure. Each pump device is composed of ...

A short pulse train with pulsewidth was generated in a quantum dot mode-locked laser (QD MLL). Due to the short dispersion length, it is required to include group-velocity dispersion (GVD) in modeling ...
